ABSTRACT:
An image display apparatus comprises a line buffer unit which stores binary image data, the binary image data being divided into a plurality of line portion data, each line portion data having a fixed length. Pattern matching units are connected in parallel with the line buffer unit and receives the line portion data respectively, each pattern matching unit determining whether an input pattern of a related line portion data matches with one of reference patterns. When the match occurs each pattern matching unit outputs a truth signal indicating the value one, and otherwise each pattern matching unit outputs a falseness signal indicating the value zero. A judgment unit receives the truth or falseness signals from the pattern matching units and determines how many times the match with respect to one of the reference patterns occurs in succession based on the received signals, the judgment unit encoding lengths of runs for the line portion data having the fixed length based on results of the determination and storing the codes in the video memory.
